Benefits of technology
The present invention is a system for updating software images on devices such as computers and mobile devices. The invention uses image and file delta technology to minimize the number of software images required and improve performance. The system includes a secure partition on the local storage medium for storing an alternate operating system and user data, which is constantly changing. The invention allows for updating computers to a known state image without losing user data or compromising the primary operating system. The system also includes a method for applying software updates without losing the user data or needing to restore the device to an earlier image. The invention overcomes common problems associated with updating software images and ensures that software updates are efficient and effective.
Problems solved by technology
As described previously, one of the major problems with updating an image on deployed devices is that the image on each device is constantly changing which makes it difficult to know if required software updates will work on each device.
This method greatly reduces the time needed to recover back to an earlier image.

Embodiment Construction
[0036]The current system is to provide a method, system and software to update the operating system and applications on devices already in the field. In a preferred embodiment, the present system updates the device software (without losing any user data that is stored on the local device) while “cleaning” the device from viruses and spyware thereby improving success rate compared to prior art. To do so, the device must first be rolled back to a clean (functional) restore point. Otherwise, unwanted changes to the operating system image will be included in the update process and will accumulate with each successive update. For performance gains, the present system may keep track of all sector-based changes to the device to enable a quick roll back to the original image at the appropriate time. However, the current invention is still relevant even if the entire image is restored to obtain a known-state image.

A method and system for updating or recovering a computer device's software image using a single portable operating system image stored on a bootable, secure partition on local storage (hard drive); a method and system utilizing delta image patching technology to allow the single image to work on a large number of diverse computer device platforms; and a method for distributing software patches and updates via a, secure local partition to ensure patches and updates are applied to well known software images that have not been modified to include malicious software and do not include any other undesirable changes that have been made to the primary, running operating system image.
